node.js - 在 Ubuntu 14.04 1and1 虚拟服务器上安装 Node

Question

我有一个运行 Ubuntu 14.04 的 1and1 虚拟服务器。将 /etc/apt/sources.list 更正为官方列表后，我尝试安装 nodejs 和 npm(稍后安装 bower)。我遵循了 https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-an-ubuntu-14-04-server 下可用的指南.

一切正常，直到我想安装 npm。已安装最新版本的nodejs:

root@somewhere:~# node --version
v0.10.30

当我尝试安装 npm 时出现以下错误:

root@somewhere:~# apt-get install npm

是的，我运行了几次apt-get update。有人知道如何解决这个问题吗？

root@somewhere:~# lsb_release -rc
Release:    14.04
Codename:   trusty

快速搜索会得到这个高度赞成的 answer .总之，首先尝试:

sudo apt-get clean

这将清除 .deb 文件的本地缓存。我那不起作用，请尝试运行:

sudo apt-get -f install

-f 代表“修复损坏”，而不是像其他一些命令那样强制执行。当我在使用另一个包时遇到这个问题时，这对我有用，但是如果这些命令都不起作用，那么答案中有很多细节。即使这些为您解决了问题，这也是一本非常有趣的读物。
